setup.sh: add OBMP_AUTH_MODE for local vs authelia bootstrap

The bootstrap previously hard-required OBMP_DOMAIN and OBMP_COOKIE_DOMAIN
even when a user just wanted a local lab deployment with Grafana's built-in
login -- those vars only feed Authelia's session-cookie domain and the
public URL it lives behind. On a fresh host with no FQDN this made
./setup.sh impossible to pass without inventing dummy values.

New OBMP_AUTH_MODE=local|authelia in .env (default local) gates the FQDN
validation, Authelia secret generation, Authelia config rendering, and the
auth-profile image pull/build. setup.sh also writes GF_SERVER_ROOT_URL into
.env -- http://HOST_IP:3000/grafana/ for local, https://OBMP_DOMAIN/grafana/
for authelia -- and docker-compose.yml now reads ${GF_SERVER_ROOT_URL}
instead of hardcoding the apodacalab.com fallback.

Back-compat: an existing .env with no OBMP_AUTH_MODE but a real OBMP_DOMAIN
or an existing AUTHELIA_SESSION_SECRET is inferred as 'authelia' and the
mode is persisted -- a re-run on a live Authelia host won't silently flip
it to local and break the next docker compose up.
